Trading Intern

The interview was an about an hour long and was of course very quant based. It began with fifteen minutes of "pre-interview" where a series of basic algebra, probability etc questions were asked. It was rather deceiving because these questions built your confidence and set a positive mood for the rest of the interview. But once the first question of the actual interview was asked, this feeling quickly diminished and you feel stumped. Other than what I have read, I can not say first hand what the other interviews are like.
